v4.5.15.9 release

v4.5.15.9 has two bug fixes and one improvement.

Significant improvement

• The status drop-down list in the search panel now displays workflow statuses with the same name only once. For example, the content type Article has two workflows, and both of them have a status named Review. Starting with this release, the status Review appears only once in the status drop-down list.

Significant defects addressed

• Corrected an issue causing assignment of unitialized objects instead of null values to copied assets.
• Corrected an issue causing deletion of a scheduled revision when the option is to replace (instead of merge with) the live version.
